A cistern inside a house contains a candelabrum, whose lamp-stand protrudes up-ward. An olive-pressing basket lies on [the lamp-stand] in such a way that if the can-delabrum were removed, the olive-pressing basket would rest on the cistern. Beis Shammai say: The cistern remains tahor, and the candelabrum becomes tamei; whereas Beis Hillel say: The candelabrum also remains tahor. They both agree that if removing the candelabrum causes the olive-pressing basket to fall, everything becomes tamei.
